Problems solved by technology

This problem means that premixed formulations of multiple active agents may not be suitable as these premixed formulations may have fixed ratios of active ingredients that cannot be changed by the healthcare professional or user
[0006] Additional problems arise where multiple drug compound treatments are required, as many users cannot cope with having to use more than one drug delivery system or make the necessary precise calculations for the required dose combination

Embodiment Construction

[0042] The drug delivery systems of the present disclosure deliver variable doses of a first medicament (primary drug compound) and limited / controlled doses of a second medicament (secondary drug compound) via a single output or drug dispense interface. The user's setting of the dose of the primary medicament automatically controls / limits the settable dose of the second medicament. In one example, the drug delivery interface is a needle cannula (a hollow needle). figure 1 A multi-dose injection device is generally shown capable of setting and delivering both a first medicament dose and a second medicament dose through a single dose setter and a single dispense interface. Such an injection device may be modified such that it allows a user to set a dose of the second medicament, wherein the settable dose of the second medicament is controlled in accordance with the amount of the set dose of the first medicament. figure 2 An example of such an improved drug delivery device is s...

Abstract

The invention relates to a drug delivery device having a dose limiting system. The drug delivery device includes a first dose setting mechanism (205) operably coupled to a primary reservoir (212) holding a first medicament (214). The first dose setting mechanism includes a first dose setter (208) and is a variable dose setting mechanism. The device further includes a second dose setting mechanism (204) operably coupled to a secondary reservoir (216) holding a second medicament, and the second dose setting mechanism includes a second dose setter (230). Still further, the device includes a dose limiting system (206). The dose limiting system operably couples the variable dose setting mechanism and the fixed dose setting mechanism. Further, the dose limiting system is configured to limit a settable amount of a dose of the second medicament a user can set using the second dose setter based on an amount of a variable dose that a user sets using the first dose setter.

Description

technical field [0001] This patent application relates to medical devices and methods for delivering at least two pharmaceutical agents from separate reservoirs using a device with only a single dispense interface. The drug formulations are contained in two or more multi-dose reservoirs, containers or packages, each containing separate (one drug compound) or premixed (co-formulated multiple drug compounds) drug formulations. The disclosed methods and systems are of particular benefit where therapeutic response can be optimized for a particular target patient population through definition and control of the treatment regimen. Background technique [0002] Certain disease states require treatment with one or more different agents. In order to deliver an optimal therapeutic dose, some pharmaceutical compounds need to be delivered in a specific relationship to each other. The disclosed methods and systems are of particular benefit where combination therapy is desired but not p...
